Embodiment 1

[0013] A 1676mm and 1000mm double-gauge sleeve turnout, such as figure 1 As shown, it is mainly composed of a switch and a fixed frog; the switch includes three fixed basic rails and three linked switch rails.

[0014] The three basic rails are 1676mm straight-strand basic rail 1, 1000mm straight-strand basic rail 2 and common curved-strand basic rail 3, and the three point rails are 1676mm curved point rail 5, 1000mm curved point rail 6 and shared straight point Track 7. In this embodiment, the linkage mode of the three point rails is that each point rail is fixedly connected with multiple tie rods, and the multiple tie rods are arranged in parallel at intervals and perpendicular to the 1676mm straight stock basic rail and the 1000mm straight stock basic rail; two of the tie rods A power device is connected to provide power for pulling the switch rail.

[0015] The fixed frog is mainly composed of a two-way obtuse angle frog 11 arranged at the intersection of the 1000mm str...

Abstract

The invention provides a 1676 mm and 1000 mm double-rail-distance mixed gage turnout. The 1676 mm and 1000 mm double-rail-distance mixed gage turnout is mainly composed of a strip switch and a stiff frog. The strip switch comprises three fixed basic rails and three linked point rails. The three basic rails are the 1676 mm straight-strand basic rail, the 1000 mm straight-strand basic rail and the common curve-strand basic rail; and the three point rails are the 1676 mm curve point rail, the 1000 mm curve point rail and the common linear point rail. The stiff frog is mainly composed of a bidirectional blunt angle frog, the first acute angle frog and the second acute angle frog. A line overlapping scheme is provided for 1676 mm width rails and 1000 mm meter gage rails, and in the situation that the space is confined and guardrails cannot be arranged, bidirectional blunt angle frogs with a self protection function are designed.

Description

technical field [0001] The invention relates to the technical field of double-gauge sheathed turnouts, in particular to a 1676mm and 1000mm double-gauge sheathed turnout. Background technique [0002] In order to satisfy two kinds of trains with different gauges passing through the turnout, two sets of same-direction single-opening turnouts with different gauges can be nested together to form a looped turnout. Among the looped turnouts, the three-track looped turnout is the most commonly used form, one of which is a common track, and the other track is set according to the parameters of the vehicle wheel set. [0003] Commonly used turnout gauges include 1435mm standard gauge and 762mm inch gauge gauge, 1435mm standard gauge and 1000mm meter gauge gauge. CN 104452487 B, an invention patent publicly authorized by the State Intellectual Property Office on February 10, 2016, discloses a three-gauge turnout that simultaneously satisfies 1435mm standard gauge, 1067m gauge and ...
